Answer:

y = \dfrac{1}{2}x

Step-by-step explanation:

The standard equation of direct variation is

y = kx

where k = constant of variation

We start with

y = kx

Since we are give one ordered pair, we use its coordinates for x and y, and we solve for k. We are told that when x = 14 ounces, y = $7.

7 = k * 14

k = 7/14

k = 1/2

Now that we know k = 1/2, we can write the direct variation equation:

y = \dfrac{1}{2}x

In a multiple regression analysis what would likely be the culprit of a dramatic increase in the P-value of one of the variables
makvit [3.9K]
This can happen if you add another independent variable to your regression model that is strongly correlated to some other variable already in the model.
This is called multicollinearity. 
If there is a high correlation between your independent variables can lead to problems.
<span>It can lead to increased variance of the coefficient estimates and make the estimates very sensitive to minor changes in the model.</span>

Teri score 64 points in the first 8 basketball games she played in she scored the same number of points in each game write and s
kozerog [31]
Well, the easiest way to go about this is to take out the number of games played (temporarily, we'll need that number later.) 
We'll make y the points per game and x the number of games.
Now the way to find this out is to divide the number of points by the number of games so:
y = 64/x

now we know x is 8 so we need to solve for y

y = 64/8
y = 8

Teri scored 8 points per game.

One angle in a triangle has a measure that is three times as large as the smallest angle. The measure of the third angle is 40 d
fredd [130]

The measure of the largest angle is 84°

<h3>How to compute the value?</h3>

It should be noted that the total angles on a triangle is 180°.

Let the smallest angle = x

Second angle = x + 40

Third angle = 3x

Therefore 3x + x + x + 40 = 180

5x = 180 - 40

5x = 140

x = 140/5

x = 28

Therefore, the largest angle will be:

= 3x

= 3 × 28°

= 84°

Therefore, the measure of the largest angle is 84°
